I am trying to implement a button into a fragment in order to use the soundPool in order to play a sound with a button. At the moment the playSound1 is coming up as never used and I have tried to implement the onClick Method but it is now coming up saying it cannot resolve the method. How do I link the soundPool to a button in a fragment? this is the .java file
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
Clubb1 = new SoundPool(10, AudioManager.STREAM_MUSIC, 1);
clubb1Id = Clubb1.load(getActivity(), R.raw.clubb1, 1);
// TODO Auto-generated method stub
return inflater.inflate(R.layout.fragment_one_layout, container, false);
Button buttonA = (Button) findViewById(R.id.buttonA);
buttonA.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
}
public void playSound1()
{Clubb1.play(clubb1Id,1,1,1,0,1);}
});
Change your method to :
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
Clubb1 = new SoundPool(10, AudioManager.STREAM_MUSIC, 1);
clubb1Id = Clubb1.load(getActivity(), R.raw.clubb1, 1);
View rootView = inflater.inflate(R.layout.fragment_one_layout, container, false);
Button buttonA = (Button) rootView.findViewById(R.id.buttonA);
buttonA.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Clubb1.play(clubb1Id, 1, 1, 1, 0, 1);
}
});
return veiw;
}
You did a lot of mistakes here. So im not sure that my approach help you enough ) Write your program result into comment and we`ll try more.
There are multiple mistakes in your code.
You return a value way to early, the code beyond your return statement isn't executed
You're inflating the View, but all your inner elements eg your button is in that view so you have to find that view by id in that view.
I corrected it:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View root = inflater.inflate(R.layout.fragment_one_layout, container, false);
Clubb1 = new SoundPool(10, AudioManager.STREAM_MUSIC, 1);
clubb1Id = Clubb1.load(getActivity(), R.raw.clubb1, 1);
Button buttonA = (Button) root.findViewById(R.id.buttonA);
buttonA.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
}
public void playSound1()
{Clubb1.play(clubb1Id,1,1,1,0,1);}
});
return root;
}

I am new to Java/android develop and trying to follow instructions from android site but cannot find clear answer to implementing onclicklistener in fragment. Please help me why its keep crashing in runtime when I click.
public class TestFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_mngr_user, container, false);
return v;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mDBhelper = new UserBaseHelper(getActivity());
// Capture our button from layout
TextView TextviewShow = (TextView)getActivity().findViewById(R.id.text_show);
// Register of onClick listener with the implementation above
TextviewShow.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// do something when the text_show is clicked
displayInfo();
}
});
}
.....
}
try this
use this
TextView TextviewShow = (TextView)v.findViewById(R.id.text_show);
instead of this
TextView TextviewShow = (TextView)getActivity().findViewById(R.id.text_show);
change your code as below
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_mngr_user, container, false);
// Capture our button from layout
TextView TextviewShow = (TextView)v.findViewById(R.id.text_show);
// Register of onClick listener with the implementation above
TextviewShow.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// do something when the text_show is clicked
displayInfo();
}
});
return v;
}
Try this
public class TestFragment extends Fragment {
View v;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
v = inflater.inflate(R.layout.fragment_mngr_user, container, false);
return v;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mDBhelper = new UserBaseHelper(getActivity());
// Capture our button from layout
TextView TextviewShow = (TextView)v.findViewById(R.id.text_show);
// Register of onClick listener with the implementation above
TextviewShow.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// do something when the text_show is clicked
displayInfo();
}
});
}
.....
}
Move your code from onCreate() method to onCreateView() method and change the following code
From
(TextView)getActivity().findViewById(R.id.text_show);
to
(TextView)v.findViewById(R.id.text_show);
I am very new to android and I am trying to make CardView by programmatically, I am using Fragment. By setting an OnClick on the button I am able to create cards in my layout. The issue is after closing the activity cards are not showing.
How can I save the cards, so after closing the activity cards should be there?
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getActivity().setTitle("Okhlee");
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
view = inflater.inflate(R.layout.hawker_jobs_fragment_layout, container, false);
context = getContext();
button = (Button) view.findViewById(R.id.hawker_job_add_card_view_button);
button.setOnClickListener(this);
relativeLayout = (RelativeLayout) view.findViewById(R.id.hawker_job_relative_layout);
return view;
}
#Override
public void onClick(View v) {
createCardView();
}
/*Adding cardview programmatically function */
private void createCardView() {
CardView addedCardView = new CardView(context);
layoutParams = new LayoutParams(LayoutParams.WRAP_CONTENT, height);
addedCardView.setLayoutParams(layoutParams);
addedCardView.setPadding(10 ,10, 10, 10);
addedCardView.setRadius(15);
addedCardView.setCardBackgroundColor(Color.BLUE);
addedCardView.setMaxCardElevation(30);
addedCardView.setMaxCardElevation(6);
relativeLayout.addView(addedCardView);
}
Sorry for my bad English.
You can use SharedPreferences in order to know whether you should display the card.
Here's a sample code using your original one -
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
view = inflater.inflate(R.layout.hawker_jobs_fragment_layout, container, false);
context = getContext();
button = (Button) view.findViewById(R.id.hawker_job_add_card_view_button);
button.setOnClickListener(this);
relativeLayout = (RelativeLayout) view.findViewById(R.id.hawker_job_relative_layout);
SharedPreferences sharedPref = getPreferences(Context.MODE_PRIVATE);
boolean shouldDisplayCard = sharedPref.getBoolean("should_display_card", false);
if(shouldDisplayCard)
createCardView();
return view;
}
#Override
public void onClick(View v) {
SharedPreferences sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPref.edit();
editor.putBoolean("should_display_card", true);
editor.apply();
createCardView();
}
Im getting an error when I press the button in my fragment view. The button is rendered but when I click it I get the following error:
09-23 18:29:01.242 9332-9332/? E/AndroidRuntime﹕ FATAL EXCEPTION: main
java.lang.NullPointerException
at foit.startingpoint.nl.androiddrawer.LocatiesFragment.onCreateView(LocatiesFragment.java:28)
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
Button button = (Button) getView().findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent myIntent = new Intent(LocatiesFragment.this.getActivity(), SecondActivity.class);
startActivity(myIntent); }
});
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_locaties, container, false);
}
your initializing is incorrect, you must do as following code:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_locaties, container, false);
Button button = (Button) view.findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent myIntent = new Intent(getActivity(),SecondActivity.class);
startActivity(myIntent);
}
});
return view;
}
as onCreateView not finished getView is null in your code so you must create one view and use that.
You cannot simply getView() from nowhere when finding button id. First layout is inflated.
View view = inflater.inflate(R.layout.fragment_locaties, container, false);
Button button = (Button) view.findViewById(R.id.button);
...
return view;
I'm trying to convert a layout so that it will include fragments.
One of the views is an ImageButton that has a listener.
The code worked fine as an Activity but makes trouble as a Fragment...
First problem was that I couldn't use findViewById,
but I was able to find the answer for that here and fixed it with getView().
I can't find an answer to the second problem...
after I declared:
ImageButton camBt = (ImageButton)getView().findViewById(R.id.button1);
I want to set an on click listener:
camBt.setOnClickListener(listener);
But it keeps acting like the ImageButton (camBt) doesn't exist...
I don't even know what's the problem... it worked fine in the Activity...
Here's the full code.
Many thanks!
public class CameraFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View V = inflater.inflate(R.layout.camera_fragment, container, false);
return V;
}
ImageButton camBt = (ImageButton)getView().findViewById(R.id.button1);
camBt.setOnClickListener(listener);
ImageButton.OnClickListener listener = new ImageButton.OnClickListener()
{
#Override
public void onClick(View arg0)
{
Camera.open().getParameters();
}
};
}
Move
ImageButton camBt = (ImageButton)getView().findViewById(R.id.button1);
camBt.setOnClickListener(listener);
inside onCreateView().
Like
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.camera_fragment, container, false);
// Here it is
ImageButton camBt = (ImageButton)v.findViewById(R.id.button1);
camBt.setOnClickListener(listener);
return v;
}
And one more thing you need to understand that variable name should starts with small letter. So you should use View v instead of View V.
You should add
ImageButton camBt = (ImageButton)getView().findViewById(R.id.button1);
camBt.setOnClickListener(listener);
inside onCreateView() like:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View V = inflater.inflate(R.layout.camera_fragment, container, false);
ImageButton camBt = (ImageButton)v.findViewById(R.id.button1);
camBt.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
}
});
return V;
}
public class CameraFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View V = inflater.inflate(R.layout.camera_fragment, container, false);
ImageButton camBt = (ImageButton)V.findViewById(R.id.button1);
ImageButton.OnClickListener listener = new ImageButton.OnClickListener()
{
#Override
public void onClick(View arg0)
{
Camera.open().getParameters();
}
};
camBt.setOnClickListener(listener);
return V;
}
}
I have an app that uses fragments, its working ok,
but I have now to implement some pop ups when a button gets tapped,
I am following this tutorial "Example of using PopupWindow"
But I get this errors:
Multiple markers at this line
- LAYOUT_INFLATER_SERVICE cannot be resolved to a variable
- The method getBaseContext() is undefined for the type new
View.OnClickListener(){}
here my .java
public class Tab2HeadH1 extends Fragment implements OnClickListener{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.tab_2_head_buttons, container,false);
//Buttons
Button buttonNose = (Button) view.findViewById(R.id.button_pop_nose);
buttonNose.setOnClickListener(new OnClickListener() {
#Override
public void onClick(final View v) {
//aqui tus tareas,,
LayoutInflater layoutInflater = (LayoutInflater)getBaseContext().getSystemService(LAYOUT_INFLATER_SERVICE); //ERRORS HERE!!
View popupView = layoutInflater.inflate(R.layout.popup, null);
final PopupWindow popupWindow = new PopupWindow(
popupView,
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
}
});
Button buttonEye = (Button) view.findViewById(R.id.button_pop_eye);
buttonEye.setOnClickListener(new OnClickListener() {
#Override
public void onClick(final View v) {
// onLoginClicked(v);
Toast.makeText(getActivity(), "ss9 eye",
Toast.LENGTH_SHORT).show();
}
});
return view;
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
((TabActivity)getActivity()).setHeader("TAPING APPLICATION");
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
}
}
}
SO, how can I fix this problem??, to show my pop up from tapped button in my fragment??
call
LayoutInflater layoutInflater = (LayoutInflater)**getActivity()**.getBaseContext().getSystemService(LAYOUT_INFLATER_SERVICE);
Atleast it won't show error onBaseContext() as now it take from the associated activity
EDIT
Try this,
LayoutInflater layoutInflater = (LayoutInflater)getActivity().getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
View myFragmentView = inflater.inflate(R.layout.yourlayout, container,false);
//inside button onclick write the code given below
View popupView = inflater.inflate(R.layout.address, null);
}
